Apalachia Dam

Please note! Water release schedules often change without notice due to unanticipated changes in weather conditions and power system requirements.

Water release schedules are updated periodically throughout the day. Next-day release schedules are usually available by 6 p.m. of the current day.

Observed water levels also are updated periodically throughout the day. Predicted water levels are updated at least once a day, by 1 p.m. Eastern time, and may be updated more frequently when conditions warrant.

Times shown below are local times.

TVA provides special water releases from a number of dams for fishing, boating, and rafting. View the schedule and calendar for recreational releases here.

Use caution near dams. A large amount of water may be discharged without warning at any time. Your safety depends on obeying all posted safety regulations and warnings. Learn more here.
